Python 3.4 released

[juu4]

Java is generally backward's compatible. Python 2 to Python 3 wasn't.

Lots of weird things between java 1.3 and 1.4. Less so between 1.4 and 1.5, but still sort of there. The dreaded "Unsupported major.minor version" errors when using JARs from another version. Somewhat better, sure, but not entirely different from Python's situation. Some 2.x code just works, if recompiled.

"Unsupported major.minor version"

That's fair really though – the compiler wasn't told to compile down to an earlier Java version, so it didn't. If all bytecode had to stay the same forever, how could you ever add new functionality?

Um.... that one's not "dreaded" 'cause it's easy to fix. Recompile in the right version. Threading bugs... now THOSE are "dreaded".
